I will be presenting at the 17th International Akademie Fresenius conference on endocrine disruption (ED) which is being held online and in person in Cologne, Germany on the 12 and 13 November 2026. The meeting will focus on Legislative frameworks and Scientific Foundations, Implementation of endocrine assessment across sectors, advanced assessment approaches and future testing strategies. I am presenting on “Deriving Endocrine Disruptor Predicted No Effect Concentrations (PNEC) for the Environment” based on the outputs from a recent collaboration with England’s Environment Agency (EA 2026). The presentation will cover an overview of the approach taken to derive a PNEC for an ED substance with a focus on estrogen, androgen and steroidogenesis modalities, PNEC derivation applied to case study substances 4-tert-octylphenol, nonylphenol, and ethinylestradiol (EE2) and discussion of considerations for deriving threshold levels for ED substances.
The meeting promises to include some interesting discussions, and I look forward to catching up with colleagues. Please don’t hesitate to reach out if you want to learn more about wca’s presentation at this conference.
